Significant development of agrarian communities was the spread language?

It's not accurate to say that the spread of language was a significant development of agrarian communities. While language was crucial for their development, it was a pre-requisite rather than a direct result.

Here's why:

* Language preceded agriculture: Humans developed language long before the rise of agriculture. It was essential for communication, cooperation, and social organization, which were key for early human survival.

* Agriculture facilitated language development: The transition to agriculture led to increased social complexity, requiring more nuanced communication. This, in turn, contributed to the development and refinement of language.

* Language as a tool for agrarian development: Language was vital for transmitting knowledge about farming techniques, coordinating labor, and establishing trade networks. This facilitated the growth and sustainability of agrarian communities.

In summary, language was a foundational element for human development, including the emergence of agrarian societies. While agriculture spurred the refinement and expansion of language, it was not the primary force driving its spread.
